| Abstract: | Moment-resisting hardwood dowel joints connecting two members at right angles to each other, such as post and beam joints, would easily fail by splitting of the member into which hardwood dowels are inserted perpendicularly to the grain. In this research, two methods were discussed to prevent the member from splitting ; one is to use long dowels for the joint dowels and the other is to use reinforcement dowels together with the joint dowels. Dowels 12 mm in diameter made of hard maple (Acer saccharum) were glued into post and beam or sill members of SPF glulam with polyurethane adhesives to make the above-mentioned two types of specimens. As a result of moment tests, both the two types were found to be effective in preventing the members from splitting. The observed maximum moments were more than 75% of the estimated values assuming that the joint specimens fail by withdrawal of the joint dowels. Racking tests of hardwood-dowel connected wall-frame specimens of 910 mm in width and 2730 mm in height using reinforcement dowels were conducted to verify the performance of the joints with the reinforcement dowels. As a result, the tested frame type was found to have comparatively large racking resistance ; the shear wall multiplier was evaluated to be 1.5. |
